Title: Sewage treatment using percolation unit with pre- and post-clarification tanks - in which water is recycled from buffer space downstream of percolation tank to stabilise rate of flow through percolation unit
Inventor: CORDES WILLI
IPC: C02F3/04
Filed: 1992-11-05
Abstract: A percolation sewage treatment plant has one or more pre-clarification tanks (1), a percolation tank (3) with packing material (2) and a post-clarification tank (4). An inlet pipe (5) brings the waste water to the pre-clarification tank, and a second pipe (6) transfers it to the percolation tank. The post-clarification tank has an outlet pipe (7), and a return pipe (8) leads from the outlet section of the percolation tank back to the pre-clarification tank. The novel feature is that a buffer space (9) is provided downstream of the percolation tank. From this space the water returns to the pre-clarification tank via the pipe (8) or to the percolation tank via a return pipe (10). Also claimed is procedure for operating this plant, in which the liquid leaving the percolation material (2) is collected in the buffer space and is periodically returned in part to the percolation chamber. Once a required minimum liquid level in the buffer space has been reached liquid is delivered from the buffer space to the post-clarification tank. USE/ADVANTAGE - Used in sewage treatment esp. for e.g. individual dwellings, hotels etc.. The construction of the plant is simple and it provides reliable and effective waste water treatment even in the case of varying water flow rates.

Patent DE-4301591-A1 (DE)
Inventor: TANAKA HIROSHI
IPC: B60W10/02
Filed: 1993-01-21
Abstract: A motor vehicle has a continuously variable automatic transmission, an automatic clutch provided between the engine and the automatic transmission, an antilock brake system (ABS). An ABS signal is produced when the ABS is operated. In response to the ABS signal, the automatic clutch is released so as to efficiently operate said antilock brake system without belt slipping. The idling speed of the engine may be increased when the clutch is disengaged to ensure sufficient pressure output from the pump supplying the controlling hydraulic system.

Inventor: STEINBERGER NIKOLAUS
IPC: D21F1/40
Filed: 1994-05-17
Abstract: A hollow cylinder without internal support is a roller belonging to a paper machine press. Here, in the cylinder's longitudinal direction the variably treated wall thickness profile is so determined by a computer program that roller deflection resulting from self and lengthwise loading is minimal. The procedure comprises the following steps: an extreme value problem is formulated; the first derivative is determined and set to zero; in the process certain fixed-point theorems are applied and the wall thickness profile is ascertained.; scalar products were integrated out and Green's function precisely formulated. Finally, there are constants which no longer depend on the profile shape.

Title: High pressure gas channel burst disc system
Inventor: NAUMANN KARL WIELAND
IPC: F16K17/40
Filed: 1994-05-27
Abstract: The mandrel to burst the diaphragm is formed by a piston punch (4) just short in outside diameter of the inside diameter of the retaining ring (2). An accelerator (6) accelerates the piston so it punches out the diaphragm (1) all the way along the inside of the ring (2). The piston movement is forcibly guided and the low pressure space (9) of the flow-channel comprises a cylindrical chamber having a wall gas port (16) close to the diaphragm acting as bursting disc. The chamber is closed off on the non-diaphragm part and can accommodate both piston and accelerator. With the chamber lying between the non-diaphragm edge of the port (17) and the punching edge of the piston when this (4) is forced back by the gas flow, a dead-end space is created to accept the punched part of the diaphragm, using an endstop in the high pressure space (11) close to the diaphragm to prevent the punched diaphragm part penetrating the high pressure space. The centre bolt acting as endstop produces a gas passage annulus between bolt and diaphragm-sealed outlet from space (11).
